Excel-G's are a fixed-damping shock with a price that's a little lower than the adjustable models. (They're slightly firmer than stock shocks, though not by much.)
Note that these have traditionally been called "GR-2," but KYB recently renamed them. So now they are Excel-G. Same product, just a different name.
Set of four struts/shocks. Fits all 2008-2010 Subaru WRX hatchback and sedan. These will also fit 2011-2014 WRX, but you will need to add a 1/2" front strut spacer if you use 2011-2014 springs.
